Both cubic zirconia and moissanite are popular choices for fake diamond rings, but they have different properties. Moissanite is known for its remarkable brilliance and fire, making it a closer match to real diamonds. Cubic zirconia is less brilliant but still provides an impressive sparkle at a lower cost.

Lab-grown diamonds have become a red-carpet favorite, with celebrities leading the way towards a more sustainable and ethical future for engagement rings. These stunning stones are just as sparkling and beautiful as mined diamonds, but without the environmental or social impact.

1.00 Carat Because it's the most popular weight, diamonds experience a price jump at 1.00 ct. The price jump is especially high for round diamonds, and, at this weight, you'll get the most savings by choosing a fancy shape. With a budget of $4,500, you can find a great one-carat diamond.

Whatever their origin, these gorgeous gems have become trendy diamond alternatives due to their shimmering aesthetic and lower price tag.
